easy, rugged tug to operate. Thirsty compared to super cubs, robins etc but break less often. 260D was the nicest model I've flown and had the advantage of having the fuel in the wings which is slightly better in a crash as in the B its in a tank in front of you. I used to get about 13 tows between fills and put in 100 or so litres - that was towing to an average of 2500 (from memory and I'm old now so my brains have shrivelled up). If you cool them sensibly on the way down (initially you can't go down if you want to let the cylinders cool at a sensible rate) they tend not to crack and I don't think I've ever suffered or caused a cracked cylinder in a pawnee. If you get up and back on the ground in under 7 mins you have come down too quickly and will crack cylinders (maybe a bit quicker if you are good at climbing in the lift and descending in the sink). Don't let the airflow drive the engine on the way down as the balancer system gets unhappy and ruins the bearings. Very nice to field retrieve in because of the agricultural undercarriage and the wire cutters up the screen and on the legs. Inspires a bit of confidence. Lots of rudder authority when the glider pilots are going walkabout on tow. Dual tows are easy. Called a pawnee because if you fly one enough you will end up with a poor knee.
Great tug well suited to rougher fields and turbulent conditions but its probably possible to operate a robin or a cub for quite a lot less money.
